Talk to her and tell her what you think about it. It may or may not work. If she decides to stay with him, the best thing you can do is just be there for her. It may be hard for you but hopefully over time she will come around. The last thing you want to happen is lose a friend because she didn't realize it right away. But you do need to talk to her and make sure she is actually listening and not just seeming like it. Hope this helps and good luck!!
Don't date him.
A friend
Try to make him know that you are not a guy but a girl :)
Unfortuately, i think your friend has 'dibs', maybe in a few years :)
special friend
Nothing if it's just a friend?
theres a guy at school you like but hes dating your friend how do you tell him you like him without hurting your friend but you know that he hates you
Don't pretend you don't know he's talking behind your back. Next time he comes and treats you "nicely", spill it out, confront. He's got to grow up. A little advise, if you let me: stay away from men like this.
you stay away from the person your mom hates the guy your dating because he might be bad or treats you like a bad person.
Soon she will be dating Gino Rosati one of her close guy friend
Be honest with your friend and make sure that your friendship will last, regardless of who ends up dating the guy.
support them both
